Which factor is most commonly associated with the development of urinary tract infections (UTIs)?

The development of urinary tract infections (UTIs) is frequently associated with urinary stasis. Urinary stasis occurs when there is an inadequate emptying of the bladder, leading to a buildup of urine. This stagnant urine provides a conducive environment for bacteria to multiply, which increases the risk of infection.

In older adults, factors such as decreased mobility, medications that affect bladder function, or neurological conditions can contribute to urinary stasis. Consequently, this prolonged retention of urine in the bladder can significantly raise the likelihood of developing a UTI.

In contrast, increased fluid intake usually helps to dilute urine and encourages more frequent urination, which can flush out bacteria and potentially lower the risk of infections. High mobility typically supports better bladder function and urinary flow, reducing stasis, while good personal hygiene is essential for overall health but does not directly combat the physiological factors leading to urinary stasis.
